I think that you underestimate the design effort and debugging/testing=20 needed to ensure decent analog performance in both bandwidth and DC=20 accuracy, and without a scope to help you it gets even harder. However, as the fortune cookie taped to my monitor says, "Time is the coin of your life. It is the only coin you have and only=20 you can determine how it will be spent." Just my 2c. Good luck with your EE adventures, however you choose to=20 spend your coin. J V G wrote: > On Fri, Feb 18, 2011 at 6:41 PM, Jesse Lackeyw= rote: > >> I 2nd this suggestion.
